Cardinals' Carlos Martinez: Will undergo additional MRI on Thursday

Martinez (lat) will head in for a second MRI to check if there has been any progress with his injury, Derrick Goold of the St. Louis Post-Dispatch reports.

Martinez isn't feeling as though his recovery is coming along as quickly as it should, so the right-hander will head for additional tests. This should provide the club with a better gauge of Martinez's eventual return date. There hasn't been much word on when he might be able to make his next appearance.
